TECHNICAL BACKGROUND

Implant devices are devices that are adapted for being placed in e.g.human bodies or animals, and that e.g. replace body parts that have beendamaged or removed e.g. due to cancer.

In order to keep the implant device in place so that it does not movefreely within e.g. a human body cavity, it is known to fasten theimplant device in position using a fastening device.

Briefly described, the present invention provides a solution forenabling an easy and fully, i.e. 100%, reversible way of keeping animplant in place so that it does not move freely, by providing andplacing a fastening device for an implant device into e.g. a body of apatient, where the “patient” is a living creature such as e.g. a humanor an animal.

The invention is now described, by way of example, with reference to theaccompanying drawings, in which:

FIG. 1 shows schematically a fastening device 2 for an implant device 4according to one exemplary embodiment of the invention, where thefastening device 2 comprises at least two fastening sections 6, 8 (onlytwo fastening sections are shown in the figure), where a first fasteningsection 6 is arranged with a through hole 10, a second fastening section8 is arranged with a protruding part 12, and where said protruding part12 is in place in said through hole 10 in a fastening device lockingstate (for the fastening device locking state, see FIG. 2, FIG. 1 showsan unlocked fastening device state). As can be seen from the FIG. 1, theprotruding part 12 on the second fastening section 8 is arranged with athrough channel 14 having an inlet 16 and an outlet 18, said throughchannel 14 being arranged to receive an implant device feed member 20,said inlet 16 and outlet 18 being accessible from the exterior 1, 3 ofthe fastening device 2 in said fastening device locking state, whereinthe first fastening section 6 is securely locked to the second fasteningsection 8 when, in said fastening device locking state, said implantdevice feed member 20 is in place in the through channel 14 andprotrudes from both the inlet 16 and the outlet 18 of said throughchannel 14.

Said through channel 14 may be of any length, i.e. if the protrudingpart 12 is very thin, said through channel 14 could be similar to ahole.

Said inlet 16 and outlet 18 are accessible from the exterior of thefastening device 2 in said fastening device locking state, i.e. saidinlet 16 and/or outlet 18 may be accessible from one or more sides ofthe fastening device 2 in said fastening device locking state, e.g. fromone of or from some of the following sides: the outer side, the innerside, or any other side not belonging to the outer side and the innerside, of the fastening device 2, see e.g. FIG. 8 showing an embodimentwhere said inlet 16 is accessible from the exterior of the fasteningdevice 2 by being accessible from the inner side 1 of the fasteningdevice 2 and where said outlet 18 is accessible from the exterior of thefastening device 2 by being accessible from the outer side 3 of thefastening device 2.

The first fastening section 6 of the fastening device 2, and the secondfastening section 8 of the fastening device 2, may have anycross-section, e.g. a cylindrical, tubular or band shaped cross-section,where a band shaped cross-section is shown in the figure for both thefirst fastening section 6 and the second fastening section 8, and wherethe cross-section of the first fastening section 6 does not have to bethe same as the cross-section of the second fastening section 8.

The first and the second fastening sections 6, 8 may be arranged on thesame fastening unit or on separate fastening units, where an embodimentwhere the first and the second fastening sections 6, 8 are arranged onthe same fastening unit 22, is shown in the figure.

None or at least one of the fastening units may be attached to theimplant device 4, and the implant device feed member 20 may be or not beattached to a fastening unit, where an embodiment where no fasteningunit 22 is attached to the implant device 4 by attachment means. e.g. bychemical or mechanical means such as adhesive or suturing, and where theimplant device feed member 20 is not attached to a fastening unit 22, isshown in the figure. The inlet 16 and the outlet 18 of the throughchannel 14 arranged in the protruding part 12 on the second fasteningsection 8 may be arranged on the same side of the first fasteningsection 6 in the fastening device locking state, or on different sidesof the first fastening section 6 in the fastening device locking state,where an embodiment where the inlet 16 and the outlet 18 of the throughchannel 14 arranged in the protruding part 12 on the second fasteningsection 8 is arranged on the same side of the first fastening section 6in the fastening device locking state, is shown in the figure.

It could also be possible to arrange the outlet of the through channelarranged in the protruding part on the second fastening section toconnect to an inlet of a through hole arranged in the second fasteningsection, wherein the inlet of the through channel arranged in theprotruding par on the second fastening section and the outlet of thethrough hole in the second fastening section are arranged on differentsides of the first fastening section in the fastening device lockingstate, whereby the inlet and the outlet of the through channel arrangedin the protruding part on the second fastening section might be arrangedon opposite sides of the first fastening section in the fastening devicelocking state (not shown in the figure).

As shown in both the embodiment according to FIG. 1, and being moreclearly visible from FIG. 2, it is preferable to arrange the inlet 16and/or the outlet 18 of the through channel 14 arranged in theprotruding part 12 on the second fastening section 8 adjacent to thesurface of the first fastening section 6 in the fastening device lockingstate for minimizing any play in the locking device between the firstfastening section 6 and the second fastening section 8, but it is alsopossible to arrange the inlet 16 and the outlet 18 of the throughchannel 14 arranged in the protruding part 12 on the second fasteningsection 8 somewhat distanced from the surface of the first fasteningsection 6 in the fastening device locking state, whereby some play mayoccur in the locking device between the first fastening section 6 andthe second fastening section 8.

The first fastening section 6 is preferably detachably securely lockedto the second fastening section 8 when said implant device feed member20 is in place in the through channel 14 and protrudes from both theinlet 16 and the outlet 18 of said through channel 14, by that it ispossible to remove the implant device feed member 20 from the throughchannel 14, where after it is possible to detach the first fasteningsection 6 from the second fastening section 8, this without anysubstantial effort and without having to deform any parts of thefastening device 2.

The implant device feed member 20 may or may not be detachably ornon-detachably attached to the implant device 4.

The implant device feed member 20 may be arranged to feed hydraulicfluid, pneumatic fluid, or electrical energy or electrical signalsbetween the implant device 4 and a remote unit 24, e.g. that the implantdevice feed member 20 is arranged to feed hydraulic fluid, pneumaticfluid, or electrical energy or electrical signals to and for from theimplant device 4.

As can be seen from the figure, the implant device 4 may be arranged tobe fastened around a body part or another implanted device or member 26.Said body part may e.g. be at least one of a stomach or divided part ofthe stomach, an intestine, a closing sphincter and other part of thefood passageway. Said body part may e.g. be at least one of an urethraand other part of the urinary tract. Said body part may e.g. be a bloodvessel or heart. Said body part may e.g. be a vas deferens or uterinetube.
